到目前为止没有运气。如果有人看一看，我会非常感激。在这里查看了您的代码示例后，我认为您可以通过两种不同的方法来完成，例如将其解码为数组和使用括号符号访问
[]->$json = json_decode($result, true);
$val= $json["features"][0]["geometry"]["properties"]["kadastralegrootte"];
echo "$val";
$data = json_decode($result);
$value = $data->features[0]->properties->kadastralegrootte;
echo $value;
不起作用：（@Dogantr发布
$result$data = json_decode($result);
$value = $data->features[0]->properties->kadastralegrootte;
echo $value;
